TThese is something obvious about the Lycra that is good to keep in mind :
                - The Lycra doesn't keep heat : don't wear it without a wetsuit (you could also feel a little bit cold if you wear just a Lycra).
                - It goals is to protect you against irritations and small cuts produced by the wetsuit.
                - It is not like a T-shirt, it must stick to the skin otherwise it can cause irritations.
                - If you surf during winter, try to wear a Lycra with a high collar that is best adapted to winter wetsuits
                - You must pay attention to your Lycra like a wetsuit : you must wash it after every session with fresh water otherwise it can stink like fish.
